5.2.3 Bearings–grease lubricated

MF pumps are normally furnished with grease lubricated bearings. Grease fittings are provided on the line and

thrust bearing ends of the bearing housing; see detail below. Before starting the pump, check the bearing

frame cavities for grease and add grease as necessary. For suggested frequency and grease quantity for re-

lubrication, refer to section 5.2.6.2

Proper grease lubrication is very important. Anti-friction bearings can be over-greased as well as under-

greased. After start up, remove the grease fittings or pipe plug closest to the cover and allow the excess

grease to flow out.
